1 (a) A carrier signal 6cos(10π×106t) volt is modulated using AM by an information signal 4cos(4π×103t)+cos(2π×5×102t) volt. Determine (i) The equation for the modulated AM signal, (ii) If the modulated AM signal is fed into a 50Ω antenna, determine the a. Power in the carrier, b. Total transmitted power, c. Efficiency of the system, Note: cosAcosB=1/2cos(A+B)+1/2cos(A−B)}
